I assume the scale, which the link says on these examples on YouTube video are 1:100 but doesn't say elevation line contour intervals, is all scalable by inputting the perameters of scale you desire to model. Can you input an entire parcel of land's actual data points of elevation survey from an on site surveyor's work mapping program?
I can also see it as an on-site tool situated in a construction trailer or such and used mostly for hole corridors or a portion of the property. Does it really calculate cut and fill yardage inventory?
20 years ago already, I took some local night school vocational school cases in LandCad that could 3-D model and calculate cut and fill inventory and perameter sq footage and yardage measures. That is nothing new just on a computer screen. But, this 'hands on' is something interesting.
Now, if you could hook up and connect the modelling platform data points of contour post 3-D design and desired shaping configuration that one can model on this application to a dozer with the lazer guided blade, well that would be both interesting but alarming in the displacement of workers lost to automation and robotics. Imagine setting that remote robotic shaping task up one day, and the work goes on all night and you get there in the morning with it all pretty much rough shaped out! Or, you get there in the morning and the program went nuts, and the dozer lost contact with program and went through a house a half mile off the property site!
